To all whom it may soccer Be it known that l, "WALT R J, RioHAims, citizen of the United States, residing at Milwaukee, in the county of: Liv/mikes enl State of WlSSCODSlIi, have invented e certain new end useful lmprcvemem in Electrical Conductors for ym-mos, of which the follcwing is e iiii, clear, concise exect de script1on,-reference being lied to the accompanying drawings, forming a part 01" this specification.

My venticn relates to (lg/"name electric machines and has. for i'ts'ocject more improved and more enicient means for seouring a rigid and reliable eiecciieel contact between the carbon brushes eiidilie respeciive conductors which iced so ciiiding posts.

Having described my invention, 7 o as new and desire to secure by Patent: V

1. The combination of an electroplated o carbon brush, a flexible igtail for slitting current to or from said brush, :2

3. The combination of a, a bon b flexible 'pigtcil for "cransmi 01' from. said brush, said pigwil flattened end, a rivet soldered to sale igtail, thus flicking a rigid COBRQCU tween said flattened end and the uppfi of the brush, and a coating on the ores; pic 89 'viding a path of high electrical conductivity loci-Ween said igtail end and brush.

4. The combination of a carbon brush :1 flexible pigtail for transmitting CLU QDl, i from said brush, said igtail having a tened end, a rivet passing thro l end and the end of said brash mec ically holding said igtail in en agement with said brush, said pig-tail solie ed to said rivet, and a coating on said l vidinge path of lllgll electrical Q 5.
